I think the proposed parameters have a negative effect on downloading with transmission app. It stalls and hangs for me.

Just a theory, but maybe somebody can confirm.

Yesterday I activated the proposed paramaters.

Then started transmission - N900 hung.
Reverted to original parameters (restart).
Started transmission waited a while for it to download some, then activating proposed parameters.
Left it overnight.

In the morning, transmission was not responding, download had not progressed and BaterryGraph shows above 50% usage whole night (good, that it was on charger).
